Ben,
Thanks indeed, I did not that BSR does not elect. Aha !, that's why I can
see all the RPs on all routers with priority information.
mmm, Autorp elect the highest IP RP and send the elected RP to the
other routers,
So BSR burden the other routers with more job , Autorp announce the
winner and make the domain consisten with which RP to use.
:)

Louis,
If I'm not mistaken, the BSR does not elect RP. Instead, it compiles
the RP set from the unicast RP candidate announcements, and
multicasts this to all PIM routers using 224.0.0.13 . Each PIM router
then elects RP for each group address, based on candidate RP priority
setting, or BSR candidate hash mask.

Hi Group : I have collected the following debug out of the BSR
router , please tell me if this way of verification is valid to
know who was elected as RP
debug ip pim bsr
*Mar 1 01:25:30.175: PIM-BSR(0): RP-set for 224.0.0.0/4
*Mar 1 01:25:30.179: PIM-BSR(0): RP(1) 130.100.5.5, holdtime
11 sec priority 100
*Mar 1 01:25:30.179: PIM-BSR(0): RP(2) 130.100.2.2, holdtime
119 sec priority 200
in the above debug, can we say R5 was elected because of two
things : ?
1 - Lower Priority
2 - RP(1) is shown as the first RP in the RP-set.
